EatThisMuch.com is a nutritional robot. You tell it your goals, it produces meal plans. It tells you how much they cost, counts the calories and offers nutritional info.

If like Joy, you eat like a rabbit, you can configure it for vegetarian or vegan offerings only. Let it know about your allergies. Decide whether you cook a lot or a little, whether you always eat “breakfasty” things in the morning, and how much protein, carbs and fats you want on average. Select from a list of favorite foods and list those you want to forever exclude. Joy went nuts excluding stuff from her daily plan: Dinner ended up being two cups of boiled beans.

Other sites like DiseaseProof.com go deeper into nutrition and give better advice, but the robot diet calculator is fun.
